Specific safety measures must be followed strictly as applicable during field execution[cite: 1]. All overarching safety protocols are covered separately in the Project HSE Plan[cite: 1].

5.1 Formwork and Falsework (F&F) Terminology

Formwork (Shuttering): Mold used to contain wet concrete until it reaches the desired shape and self-supporting strength[cite: 1].
Falsework (Staging / Centering): Temporary structure supporting permanent structural elements during erection until self-supporting status is achieved[cite: 1].
Scaffolding (Paranja): Light structural framework erected to provide safe access for site personnel[cite: 1].
Striking (Stripping): Planned, controlled dismantling and removal of formwork components[cite: 1].
Sheeting (Sheathing): Supporting surface skin in direct contact with wet concrete[cite: 1].
Joist (Batten): Primary horizontal framing member directly supporting sheeting (slabs and beams)[cite: 1].
Bearer (Runner): Secondary horizontal load-transfer member supporting joists[cite: 1].
Prop Cap: Head unit seating top bearer loads axially into vertical props[cite: 1].
Prop: Vertical load-bearing support member transferring vertical loads downward[cite: 1].
Prop Base: Baseplate unit designed to distribute concentrated axial prop forces against punching shear[cite: 1].
Prop Footing (Spreader): Load distribution member designed to transfer concentrated vertical loads to stable, unyielding foundation strata[cite: 1].
Wedge: Tapered packing block used to fine-tune levels, plumb adjustments, and facilitate easy striking[cite: 1].
Wailing / Waling: Horizontal structural member designed to resist outward hydrostatic pressures on vertical shuttering panels[cite: 1].
Stud: Vertical reinforcement member resisting lateral liquid concrete pressure against sheeting panels[cite: 1].
Soldier: Heavy vertical structural member cantilevered upward from previously poured concrete elements[cite: 1].
Yoke:
  • Columns: External horizontal framing collar encircling column forms against bulging[cite: 1].
  • Slipform: Structural frame straddling inner and outer formwork faces[cite: 1].
Stop-end (Bulkhead): Vertical shutter plate inserted to terminate concrete pours and establish controlled construction joints[cite: 1].
Back Form: Top-face formwork unit applied over inclined or sloping slab pours[cite: 1].
Bracings:
  • Horizontal: Two-way structural ties engineered to restrict the effective slenderness ratio of vertical props[cite: 1].
  • Diagonal: Inclined framing elements engineered to transfer wind and lateral forces directly through props[cite: 1].

Riband: Flat-laid horizontal member deployed to withstand lateral pressure forces[cite: 1].
Starter (Kicker): Concrete stub cast monolithically with footings/slabs to locate and secure vertical column/wall shuttering[cite: 1].
Shikanjas: Mechanical clamping brackets used to hold opposite shuttering panels or right-angled corners firmly together[cite: 1].
Four-Way Head: Top-mounted support head used to receive and support I-beams or double runners beneath slabs and beams[cite: 1].
Tripod: Three-legged base accessory used to stabilize vertical props during erection and maintain plumb alignment[cite: 1].

  • Track daily productivity, compare against project targets, and submit updates to the Project Engineer / Project Manager[cite: 1].
  • Coordinate with Safety Engineers to maintain safe field practices during erection and dismantling[cite: 1].
  • Coordinate with QA/QC Engineers to arrange timely field inspections for completed shuttering elements[cite: 1].
  • Cross-check daily site production against reports provided by Foremen[cite: 1].
  • Distribute updated structural drawings and revisions immediately to the field execution team[cite: 1].
  • Work with Surveyors to verify levels, verticality, plumbness, and line alignment before concrete placement[cite: 1].
